MEECO'S RED DEVIL 120 Furnace Cement and Fireplace Mortar

Very easy to apply which other FirePlace motors were not.Would purchase again

This product was easy to use and once it sets, is rock solid. It is recommended in the instructions to add a little water because the cement is really viscous and thick. Once water is added, the product flows and smooths better than silicone caulking! It then takes some time to dry and use; I waited about a day.I used the cement to seal in my fireplace but also later on, my boat's turbo diesel exhaust manifold. My exhaust manifold developed small holes due to rust and it would have a major pain to remove them because of space. I tried the furnace cement as it could not do any more harm and it worked! It is holding strong and no more exhaust is leaking. I've put 20+ hours on the engines and the seal is still fine. I would not recommend, however, putting this product on areas where flexing can occur because of its rigidity.Whether sealing fireplaces or exhaust pieces, this product works.

The slate panels around my fireplace fell off an broke one night. I use this to paste them back up. Seems to be holding

It does the job. Don't expect this to be a permanent solution. The material will dry and crack with time and must be regularly replaced.

After reading Coffee-Cup's review I used this product to repair 2 burned out (all the way through) tobacco pipes.Product came out of the tube in an almost liquid state so I had my doubts.Spread it evenly with my fingers and followed directions. Let set for 24 hours before applying heat with a Zippo torch and now I can smoke my favorite pipe again.Easily cleaned up excess with a paper towel.
